determining the optimal pattern for growing crops in accordance with the availability of the resources and risk factors as well as the uncertainty of agriculture sector would help the farmers, managers and economic planners in selecting the type of the product and the level of cultivation. fuzzy programming model with interval programming approach is used in this study to determine the optimal ...
Using Telser and Kataoka models of probabilistic-risky mathematical programming, the present research is to determine the optimized pattern of cultivating the agricultural products of Shoshtar region under risky conditions. In order to consider the risk in the mentioned models, time period of agricultural years 1996-1997 till 2004-2005 was taken into account. Results from Telser and Kataoka mod...
با گسترش کشاورزی آبی در بسیاری از مناطق و بروز خشکسالی در سال های اخیر،اقتصاد بخش کشاورزی با محدودیت های جدی روبه شده است. هدف این پژوهش، به کارگیری الگوی برنامه ریزی ریاضی مثبت در مدیریت منابع آب های سطحی و زیرزمینی در میان بهره برداران زراعی شهرستان قاین است.با استفاده از کالیبراسیون تابع هزینه درجه دو و سه سناریو ( کاهش 15، 65 و 85 درصدی برای بهره برداران گروه 1 و کاهش 15، 60 و 85 درصدی برای...
due to the limitation of production main resources such as water, allocation of this resources has a high importance. in order to prevent the loss of surface water and groundwater resources and also promoting economic prosperity farmers, applying policies that have been established based on the pattern of cultivation and protection of water resources, will be necessary. in such a situation the ...
The majority of biotechnologically relevant metabolites do not impart a conspicuous phenotype to the producing cell. Consequently, the analysis of microbial metabolite production is still dominated by bulk techniques, which may obscure significant variation at the single-cell level. In this study, we have applied the recently developed Lrp-biosensor for monitoring of amino acid production in si...
